Optical operation module with fingerprint identification device and operating method thereof

An optical operating module with a fingerprint recognition device, comprising:

• at least one light-emitting element, comprising:
• at least one light-emitting unit;
• a first light-exit surface;
• and
• an electrical connector, which conducts and inputs a driving current into the light-emitting unit, wherein the light-emitting unit provides at least a light to the first light-exit surface, and the light is emitted from the first light-exit surface;
• a light guide element, comprising:
• at least one first light-receiving surface forming a gap with the first light-exit surface and receiving the light from the first light-exit surface;
• at least one reflective curved surface receiving and reflecting the light from the first light-receiving surface, wherein a bent angle of the reflective curved surface is in a range from 0 to 180 degrees, and the one reflective curved surface comprises a curved surface formed with one or multiple of a straight line, a circular arc line, and a polynomial fitting curve;
• a first reflective surface receiving and reflecting the light from the reflective curved surface;
• and
• at least one second light-exit surface disposed opposite to the first reflective surface, forming an angle with the first reflective surface, and receiving the light from the first reflective surface, the light being emitted from the second light-exit surface;
• at least one display panel, a part of which is disposed on the light guide element, and the other part which is not disposed on the light guide element forming an accommodating space with the light guide element, comprising:
• a second light-receiving surface receiving the light from the second light-exit surface;
• and
• a third light-exit surface receiving the light from the second light-receiving surface, the light being emitted from the third light-exit surface;
• and
• a fingerprint recognition device disposed on the accommodating space and connected to the panel display, comprising:
• a substrate;
• a fingerprint recognition sensor disposed between the substrate and the third light-exit surface, receiving a fingerprint, and generating a fingerprint recognition signal;
• and
• a micro-control unit (MCU) recognizing an identity of a user after receiving the fingerprint recognition signal, and generating a control signal according to an identity recognition result from the user to control the light emitted from the light-emitting element.
